Description

Technical Field

[0001] The invention belongs to the field of cables, and in particular relates to an aerial optical cable laying hardware and an aerial optical cable that can be laid using the hardware. Background Art

[0002] With the continuous advancement of domestic communication network construction, the demand for overhead optical cables is increasing, and long-distance overhead optical cables require the use of hardware during the laying process.

[0003] In the prior art, the CN209657916U fixture for the head of a rod-shaped pin-type polymer crystalline silicon insulator consists of an upper fixture and a lower fixture. The upper fixture comprises a pressure plate and two cylindrical connecting rods fixed to the bottom surface of the pressure plate. The lower ends of the connecting rods are provided with limit blocks. The pressure plate, connecting rods, and limit blocks are integrally formed and made of polymer crystalline silicon. The lower fixture is a hardware gasket connected to the upper end of the rod-shaped pin insulator. The hardware gasket has through-holes at both ends. The upper and lower fixtures are mated by inserting the connecting rods into the corresponding through-holes. The limit blocks are located outside the through-holes, and the wire clamp is located between the upper and lower fixtures.

[0004] The above-mentioned existing technology has the following shortcomings: 1. The clamp is composed of an upper clamp and a lower clamp, which need to cooperate with each other during installation. When carrying multiple sets of clamps, it is easy to miss one or more of them, resulting in some clamps being incomplete; 2. The installation is to match the upper clamp and the lower clamp by inserting the connecting rod into the corresponding through hole. The limit block is located in the protruding through hole. It is not easy to remove after installation, which brings inconvenience to maintenance. Summary of the Invention

[0005] To solve the above problems, the purpose of the present invention is to disclose an aerial optical cable laying hardware and an aerial optical cable that can be laid using the hardware, which is achieved by adopting the following technical solutions.

[0006] The hook bracket is located at the bottom of the hook body, and the lower end of the hook body extends out of the hook body, and the lower end of the hook body extends out of the hook body. The limit part is located in the limit part cavity and can rotate in the limit part cavity. The outer diameter of the limit part is larger than the outer diameter of the upper end of the hook main rod cavity. The upper end of the hook main rod is located in the hook main rod cavity, and the lower end of the hook main rod extends out of the hook main rod cavity. The hook extension part has elasticity.

[0007] The overhead optical cable laying hardware has the features that the limiting part, the hook main rod and the hook hook body are integrally formed.

[0008] The overhead optical cable laying hardware has the features that the two hook extension parts and the hook hook body are arc-shaped.

[0009] The overhead optical cable laying hardware has the features that the hook main rod is further provided with a screw thread and a nut matched with the screw thread; the nut cannot fall off due to the vibration of the optical cable and its own gravity because the hook hook body is below the nut, and the fixing effect is good.

[0010] An overhead optical cable has a cable core, a wrapping layer wrapped outside the cable core, an outer protective layer extruded outside the wrapping layer, two first reinforcing members arranged inside the outer protective layer and located on both sides of the wrapping layer, and loose sleeves arranged inside the cable core. When there is one or two loose sleeves, the cable core is composed of one or two loose sleeves. When there are at least three loose sleeves, the cable core is composed of the loose sleeves and a second reinforcing member arranged between the at least three loose sleeves. At least one optical communication component is arranged in the loose sleeve. The first reinforcing member is provided with a plurality of upper and lower through insertion holes arranged at intervals along the axial direction. An upper and lower through insertion slot is arranged on both sides of the first reinforcing member along the axial direction and communicates with the insertion hole. The insertion holes and the insertion slots of the two first reinforcing members correspond to each other one by one. The outer protective layer is provided with a mounting slot at each insertion hole on the first reinforcing member, and the mounting slot exposes the inner insertion hole and the insertion slot. The distance between the two ends of each insertion slot is greater than the distance between the two hook extension parts. The width of the insertion slot is greater than the width of the hook extension part and the hook hook body. The outer diameter of the insertion hole is less than the distance between the two ends of the hook hook body and greater than the outer diameter of the hook main rod.

[0011] The overhead optical cable has the features that an annular limiting slot is further formed on the main body of the first reinforcing member along the circumferential direction of the first reinforcing member. The width of the annular limiting slot is greater than the width of the hook hook body and the width of the hook extension part. During installation, the hook extension part and the hook main rod are clamped into the annular limiting slot, so that the hook hook body supports the optical cable and cannot rotate.

[0012] The overhead optical cable has the features that the material of the loose sleeve is polybutylene terephthalate or modified polypropylene.

[0013] The overhead optical cable has the features that the material of the first reinforcing member is steel wire or glass fiber reinforced plastic.

[0014] The overhead optical cable has the features that the material of the second reinforcing member is steel wire or glass fiber reinforced plastic.

[0015] The overhead optical cable is characterized in that the outer sheath material is low-density polyethylene, medium-density polyethylene, high-density polyethylene, flame-retardant polyolefin or polyvinyl chloride.

[0016] The overhead optical cable is characterized in that the optical communication component is a G.652 type optical fiber, a G.653 type optical fiber, a G.654 type optical fiber, a G.655 type optical fiber, a G.656 type optical fiber, a G.657 type optical fiber, an A1a type optical fiber, an A1b type optical fiber, an A1c type optical fiber, an optical fiber ribbon composed of at least two optical fibers, or an optical fiber ribbon stack composed of at least two optical fiber ribbons.

[0017] The overhead optical cable is characterized in that the tape layer material is a steel tape, an aluminum tape, a water-blocking tape or a non-woven fabric tape.

[0018] During installation, the two hook extension components are kept consistent with the direction of the insertion slot, and the two hooks are inserted into the two insertion holes corresponding to the two first reinforcing members. Since the hook extension components are elastic, the hook extension components can pass through the insertion slot. Then, the hooks are rotated by 90°, so that the hook bodies support the optical cable. Further, the nut on the hook main rod can be rotated, so that the nut moves downward and fastens the first reinforcing member together with the hook body, thereby preventing the optical cable from being separated from the fitting when the optical cable vibrates.

[0019] In the present application, the first reinforcing member has a plurality of insertion holes and insertion slots, so that the optical cable is lighter than a common parallel steel wire reinforced optical cable. Meanwhile, the outer sheath of the optical cable is provided with a plurality of installation slots, which reduces the material consumption of the outer sheath and further reduces the weight of the optical cable. The hooks are located in the installation slots at the upper end of the outer sheath, so that the hooks are protected without using additional protection devices, thereby prolonging the service life of the hooks.

[0020] Therefore, the fitting has the beneficial effects of simple structure, convenient use, light weight, non-separation of parts, long service life and good fixing effect. The optical cable has the beneficial effects of simple structure, light weight and low cost. BRIEF DESCRIPTION OF DRAWINGS
